EVLSTCH03-45WPD

45W USB Type-C® power delivery 3.0 adapter based on STCH03, SRK1001 and STUSB4761. It is an isolated power supply with a standalone USB PD controller. The evaluation board implements at the primary side a quasi-resonant flyback converter based on the STCH03 controller with optocoupler feedback for voltage regulation. This controller combines a high performance low voltage PWM controller chip with a 650V HV start-up cell in the same package. The STCH03 controller drives the gate of the new 650V MDmesh™ M6 technology Power MOSFET STD7N65M6. The EVLSTCH03-45WPD is protected against destructive electrostatic discharge from the USB Type-C® connector using a dual transil array for ESD protection ESDA25L.
